The base price on the 2013 was somewhere around $19.890, or thereabouts? So $20850 is "like" $1000 more. Get the Tour and Dynamic packages and you are looking at $22700, and the 90th edition 2013 is $21,940. Add in the comfort package ($23950) and the GPS you prepped for ($995) and a topbox ($700)....you will be topping out at $25550 +tax. Max BMW lists K1600GT's at $25580. I know the math is sketchy and mixing CDN and US listings and my 'Kentucky windage' version of addition....but it looks like the GT and the RT are going to end up pretty close, so you must choose> power or weight?
